As i told before, i am not using membership test, because it costs
extra cycles e.g..
object isKindOf: CommonSuperClass
is much slower than
object class == SomeSpecificClass
if you look at NBExternalObjectType>>pushAsValue: / pushAsPointer:
it only checks that object belongs to specific class, doing
self verifyClassOf: oop is: objectClass generator: gen.
The InterpreterProxy has
#includesBehavior:ThatOf:
method, which can be used to test if given class has some specific
ancestor in its inheritance chain.
The main reason why i did not implemented the code that way is performance.
It is not that hard to implement this kind of test (see attached)
===========
Btw, we have a problem:
- NativeBoost-Core in my 3.0 image shows that last version of it is
EstebanLorenzano.116
there is not such package in NB repository. It is in Pharo30 repository..
but when i open it, it shows that it has ancestor NativeBoost-Core-cb.117
Name: NativeBoost-Core-EstebanLorenzano.118
Author: EstebanLorenzano
Time: 23 April 2013, 5:52:38.099 pm
UUID: d256a011-ce1f-4959-b5ed-37de2c7f3b84
Ancestors: NativeBoost-Core-cb.117
which is not there.
Now i cannot merge with code which is in project repository.
We should discuss, how we manage updates for NB.. because searching
packages located in
multiple repositories is tedious and counterproductive.
